Armstrong refiled and today Sparks said that while "there are troubling aspects" in this case, he is forced to side with the USADA.

"The court concludes Armstrong agreed to arbitrate with USADA and its arbitration rules are sufficient, if applied reasonably, to satisfy due process," Sparks wrote in his decision.

The USADA's Chief Executive Travis T. Tygart said it was "pleased" with the court's decision.

"The rules in place have protected the rights of athletes for over a decade in every case USADA has adjudicated and we look forward to a timely, public arbitration hearing in this case, should Mr. Armstrong choose, where the evidence can be presented, witness testimony will be given under oath and subject to cross examination, and an independent panel of arbitrators will determine the outcome of the case," the Tygart said in a statement.
